Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a skin smoothing auxiliary device. Background Technology

[0002] Because elderly, thin patients have thin and loose skin with less subcutaneous fat, their blood vessels are prone to slipping. Furthermore, single-handed venipuncture by nurses can be difficult, especially in elderly, thin patients, where the nurse may be operating with only one hand, making it challenging to stretch the skin and thus affecting venipuncture.

[0003] Currently available devices for smoothing and tightening the skin to assist in intravenous puncture procedures are as follows:

[0004] 1) Elastic tape tensioner. This device uses an elastic tape to secure the patient's arm, and tightening the tape achieves a smooth skin effect. This type of product may put excessive pressure on the patient's skin, and tearing it off can easily cause pain.

[0005] 2) A skin fixation device for intravenous puncture disclosed in CN206183738U includes a skin fixation device body with a concave cross-sectional shape. The inner surface of the skin fixation device body is elliptical, and the inner surface is provided with an anti-abrasion coating. The upper surface of the anti-abrasion coating has several parallel pleated stripes along its radial direction. This device cannot adjust the opening size. Utility Model Content

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] See Figures 1 to 6Specific Embodiment 1: A skin smoothing aid for intravenous puncture in elderly patients includes a base plate 1; it also includes a forearm support assembly, which includes an upper and lower forearm support bracket 2 and a first telescopic rod 3. The bottom of the first telescopic rod 3 is mounted on the base plate 1, and the top of the first telescopic rod 3 is rotatably connected to the forearm support bracket 2 with the front-to-back direction as the rotation center line; it also includes a wrist support assembly, which is arranged left and right with the forearm support assembly. The wrist support assembly includes a front support frame and a rear support frame arranged front and back. The front support frame includes a front limiting clamp arranged upper and lower. The wrist support assembly includes a front limiting clip 41 and a front telescopic rod 42. The top of the front limiting clip 41 and the front telescopic rod 42 are rotatably connected in the direction of rotation (with the rear-rear direction as the center line), and the bottom of the front telescopic rod 42 is slidably connected to the base plate 1. The rear support frame includes a rear limiting clip 51 and a rear telescopic rod 52, which are arranged vertically. The top of the rear limiting clip 51 and the rear telescopic rod 52 are rotatably connected in the direction of rotation (with the rear-rear direction as the center line), and the bottom of the rear telescopic rod 52 is slidably connected to the base plate 1. Both the front limiting clip 41 and the rear limiting clip 51 include arc-shaped support pieces with opposite openings, and a silicone pad is fixed inside the arc-shaped support piece. This allows the front limiting clip 41 and the rear limiting clip 51 of the wrist support assembly to flatten and clamp the wrinkled area to be punctured. The slidable arrangement of the front telescopic rod 42 and the rear telescopic rod 52 facilitates the adjustment of the distance between the front limiting clip 41 and the rear limiting clip 51 to accommodate different hand sizes of patients. The height of the front telescopic rod 42, the rear telescopic rod 52, and the first telescopic rod 3 can be adjusted to meet the different height requirements of the patient's hand. The central angle of the arc-shaped support plate is less than 160 degrees and greater than 90 degrees.

[0040] The front telescopic rod, rear telescopic rod, and first telescopic rod all include a sliding rod section and a fixed tube section, which are arranged vertically. The fixed tube section is slidably connected to the sliding rod section. A locking element is threaded onto the fixed tube section to abut against the sliding rod section. This facilitates length adjustment. Other commercially available telescopic rod structures can also be used.

[0041] A rotating gear 6 is rotatably connected to the base plate 1; a front rack 44 with its length direction in the front-to-back direction is installed at the bottom of the front telescopic rod 42; a rear rack 54 with its length direction in the front-to-back direction is installed at the bottom of the rear telescopic rod 52; the front rack 44 and the rear rack 54 are located on the left and right sides of the rotating gear 6, and the front rack 44 and the rear rack 54 mesh with the rotating gear 6. This facilitates the adjustment of the distance between the front limit clamp 41 and the rear limit clamp 51 by rotating the rotating gear 6.

[0042] A column is fixed on the base plate 1, and a pivot hole is opened in the center of the rotating gear 6, through which the column passes. A locking element 7 is threaded to the top of the column, which is used to clamp the rotating gear 6. This allows for easy loosening and clamping of the rotating gear 6 through the locking element, thereby enabling the rotation and locking of the rotating gear 6.

[0043] A front slider 43 is installed at the bottom of the front telescopic rod 42; a rear slider 53 is installed at the bottom of the rear telescopic rod 52; a groove is provided on the base plate 1 to slide and connect the front slider 43 and the rear slider 53. The front and rear sliders each include an upper and lower portion arranged vertically, with the length of the upper portion in the left-right direction being less than the length of the lower portion in the left-right direction. A front spur rack is fixed to the lower portion of the front slider. A rear spur rack is fixed to the lower portion of the rear slider. The front and rear spur racks are located within the groove. A circular hole is provided on the base plate for longitudinally inserting a rotating gear; the circular hole connects and communicates with the groove.

[0044] The first telescopic rod 3 is located at the center of the base plate 1 in the front-rear direction.

[0045] Forearm support 2 includes an arc-shaped support frame, and a silicone pad is fixed to the inner wall of the arc-shaped support frame.

[0046] The inner wall of the silicone pad has circumferentially arranged strip-shaped protrusions, with the length of the protrusions running left to right. This improves the fixation effect on the skin.

[0047] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
